BOW GUN Filed Oct. 19, 1935 llomey Patented Feb. 2, 1937 UNITED STATES PATENT OFFICE BOW GUN John Umling, Ellwood" City, Pa.

Application October 19, 1935, Serial No. 45,822 1 Claim. (Cl. zit-101.5)

This invention relates to a bow gun, the general object of the invention being to provide a simple form of trigger mechanism for releasing the string of the bow from a shoulder on the gun when the trigger is operated.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim. V

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a. top plan view of the gun.

Figure 2 is a side view thereof.

Figure 3 is a fragmentary elevation with parts in section showing the trigger means.

Figure 4 is a fragmentary vertical sectional view showing a modified form of trigger means.

Figure 5 is a similar view showing another modified form of trigger means.

In this drawing, the letter A indicates the body of the gun, the upper edge of the barrel forming part of which is formed with a longitudinally extending groove I for receiving the arrow 2 and a shoulder portion 3 isformed at the rear end of the barrel part forming a seat for a portion of the string 4 of the bow 5 of the gun which passes through a hole in the front end of the barrel portion.

Figures 1, 2, and 3 show one form of trigger mechanism for raising the string 4 out of engagement with the shoulder 3 so that the bow will cause the string to project the arrow in the usual manner. This'trigger mechanism consists of a wire 6 of substantially L-shape with one limb extending through a hole I vertically arranged in the rear portion of the barrel part of the gun, this hole I being so shaped as to permit a certain amount of movement of the said one limb. The other limb extends substantially horizontally through a longitudinally extending recess 8 in the upper portion of the rear of a barrel part of a gun, this recess forming a continuation of the groove 1 and divides the shoulder forming part 3 into two portions. A pair oi? pins 9 pass through the gun and the lower pin is engaged by the bent part at the juncture of the two limbs of the wire while the other pin is slightly raised above the said bent portion and prevents the wire from being pushed out of position or dropping out of position if the gun is inverted while permitting the horizontal limb to be moved upwardly to a suflicient amount to push the string out of engagement with the shoulder as shown by dotted lines in Figure 3.

Thus it will be seen that the bow must be 5 bent and the string placed to a portion extending across the shoulder after which the arrow is put in place and then by pulling upon the depending partoi the trigger 6 the upper portion will rock on the lower pin so that the horizontal limb moves upwardly against the string and thus push the string from the shoulder so that the bow will cause the string to strike the rear end of the arrow and thus projecting the same.

In the modification shown in Figure 4. the trigger i is in the form of a short rod or bar circular shaped in cross section and passing through an upwardly and rearwardly extending hole H in the rear portion of the barrel part of the gun with the trigger member having a slot I2 in an intermediate portion thereof through which a pin l3 passes which also passes through the body of the gun so that by pressing upon the lower end of the trigger l0 its upper end will move the cord out of engagement with the shoul-- der 3? and thus release the bow. As shown both ends of the trigger iii are slightly beveled so that the upper end forms the straight portion for firmly engaging the string to push the same out of engagement with the trigger.

In the modification shown in Figure the trigger i4 is of an elongated form and a pin l5 passes through an intermediate part thereof and through a portion of the body of the gun, the trigger tapering downwardly with its large upper end forming a cam i6 and this trigger also passes through an opening I! vertically arranged in the rear portion of the barrel part of the gun and is so formed that the trigger can be rocked therein so that when the lower end of the trigger is moved rearwardly the cam end it will move forwardly and thus raise the string out of engagement with the shoulder 3" As can be seen the trigger mechanism is of simple form so that the gun can be manufactured to sell at low cost.

It is thought from the foregoing description. that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What is claimed is:

A bow gun of the class described including a body part having a string receiving shoulder at its rear end and a substantially vertically arranged opening adjacent said rear end, a substantially inverted L-shaped trigger member having one limb passing downwardly through the opening and the upper edge of said rear portion having a. horizontal recess therein located below the shoulder for receiving the other limb of the L-shaped trigger member, a pin passing through the body and on which the curved part of the juncture of the two limbs rock and a. second pin passing through the body and located slightly above said juncture.
